Which pawn breaks are good and which ones are bad?

So I know a few general rules about pawn breaks, those mainly being :
1. Open up positions when you have better activity and king saftey
2. Look to attack pawn chains at their base

Quite often when I am watching videos of professional players (GMs, IMs etc.) they say things like “I will be very happy if I get this break in” and I couldn’t really understand why that was seeing that it didn’t really seem to adhere to either of these rules and it also seemed somewhat weakening to his king. So I guess the question I’m asking is what makes a pawn break good and what makes one bad, is there anything else I should be considering? The specific video in question that made me curious is this one if anybody is wondering:

Just my opinion:
e5 isn't a pawn break, but it does control more of the center. This could be used to support the attacking f4 which also releases the black bishop. An alternate move is e4 which would gain space and blunt the white bishop.
e4 has many of the same ideas including creating a weakness on e6 if there's an exchange on f5.
f4 was used to gain activity for the rook. It also allowed the center to remain somewhat closed.

A restatement of the general rules as illustrated in the video:
1. Open the position to exchange pieces when you're cramped.
2. Open line(s) when attacking the king.
3. To fix a weakness. This can be in a pawn chain, normally the base of the chain, or a weak pawn as e6 would have been. A minority attack is the usual example.
4. To open lines to infiltrate the opponent's position. Generally shown as getting a rook to the seventh.

Thanks for sharing an interesting video, and I hope this answer helps.

In that game black’s pawn on e6 was blocking the bishop, so after white played his pawn to e5, it had to get into the game by d7 and c6. So obviously if he’s able to play e6-e5, it saves a lot of work.

So I think part of it is looking at your pieces, and which parts of the pawn structure are good or bad for them. A pawn on d4 (for white) gives a knight the squares c5 and e5, a black pawn on c7 or c6 gives a white knight the squares in front of it
